Application filed February 1t), 1920. Serial No. 357,555.

. To all whom it may concern:

Be it known that 1, JOHN V, CUNNIFF, a citizen of the UnitedStates,-res1ding at Fall River, in the county of: Bristol and State oiMassachusetts, have invented new and.use-' is of simple and economicalconstruction and positive and certain in its operation.

Further and other objects of the invention will be manifested and setforth in the following description.

In the drawings:

Figure l is a bottom plan view of the invention, and

Fig. 2 is a side elevation, parts being shown in section.

In proceeding in accordance with the present invention, any number oiindividual structures embodying the invention may be secured to thespooling bar 1 of the machine. Brackets A are employed which areattached to the bar 1 and which carry spindles 2 upon which latter thebobbin 3 is supported. The bracket A. has a main arm a rigidly connectedthereto, the outer or free end of the nate therewith. The pivoted arm 8has an adjustable weight 10 between its ends, and at its inner end has aguide eye 11. The main arm 4: is provided with a top stop 13 and anadjustable stop 12, one for limiting the upward and the other thedownward movement of the pivoted arm 8.

In operation the thread passes from the bobbin 3, under the adjacentprong 7, over the prong 9 between the prongs 7 thence under the otherprong 7 and up over the other prong 9, thence over the curved frictionplate 5 through the guide eye ll, over the gulde rod 14 and thence tothe spool which may be operated in any manner.

It will be noted from the foregoing that as the diameter of the threadwound on the spool increases it will be necessary to feed this threadmore freely, and accordingly the pull on the thread will lift the guideeye 11 of the pivoted arm 8 just suflicient to permit tree movement ofthe thread for winding purposes, by slackening the tension on the threadas it comes from the bobbin 3. This 1s obviously; due to the iact'thatthe prongs 7 and 9 are brought nearer to the same plane, so that thethread has a straighter draw instead of a tortuous one, the latterdepicted in Fig. 2.

Having thus described myinvention, what I claim as new and desire tosecure by Letters Patent is 1. In a winding machine, a bracket forattachment to the spooling bar having a main arm formed with a curvedfriction plate, a bobbin spindle carried by the bracket, an arm pivotedto. the main arm and having a thread eye at one end, a weight adjustableon the pivoted arm, stops for the pivoted arm borne by the main arm, aplate on the main arm having spaced prongs and prongs carried by thepivoted arm and arrzinged to alternate. with the prongs of the p ate.

Specificationof Letters Patent, Patented Apr. 19, 1921 i 2. In a tensiondevice, a bracket provided v with a friction plate, a series of spacedprongs on said bracket arranged to the rear of the friction plate andapproximately alined with the lower end of said plate, an arm pivoted tothe bracket, spaced prongs carried by one end of said arm and arrangedto alternate with the bracket prongs, a thread eye on the opposite endof the arm, and a horizontal bobbin support carried by the bracket andsubstantially alined with the prongs.

3. In a tension device, a bracket provided with a friction plate, aseries of spaced prongs on said bracket arranged to the rear of thefriction plate. and approximately alined with the lower end of saidplate, an arm pivoted to the bracket, spaced prongs carried by one endof said arm and arranged to alternate with the bracket prongs, and athread eye on the arm above the plate, said plate being arranged toguide the thread from the prongs upwardly to the thread eye.

means on the bracket, an arm pivoted to the V bracket and having threadtensioning means cooperating with the first named means, and

, a thread eye on the arm, the friction member belng formed and arrangedto engage the thread after the same leaves the tensioning means and tothen guide the thread directly to the eye.

5. In a' tension device, a bracket having means forattachment to thespooling bar of awinding; machine, a bobbin support carried by thebracket, thread tensioning means on the bracket, a pivoted arm on thebracket havingthread tensioning means cooperating with the first namedthread tensioning means, and an eye on the pivoted arm arranged toreceive the thread directly from said friction member so as to move thearm upwardly at its rear end by a direct pull tion plate on the oppositeend of the bracket, 7

arm pivoted on the bracket and having athread eye on one end fordisposition adja- "cent to the spooling bar, and cooperating threadtensioning means between the opposite'end of the lever and the bracketand arranged to the rear of and adjacent the triotion plate.

7. In a tension device, a bracket, a friction plate on the bracket, apivoted arm on the bracket having a thread eye 011 its rear end, andcooperating thread tensioning means between the front end of the arm andthe bracket, said eye being located above the plate and the latter beingformed to guide the thread vertically and upwardly after same leaves thesaid tensioning means.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
